Description | This article provides a sample IPsec VPN configuration for use with iPhone and iPad. The configuration is for FortiOS v4.0 MR3, v5.0, v5.2 and v5.4. It differs from the configuration that is required for previous firmware versions. The related article provides a configuration guide for earlier firmware versions. |
Scope | This example is intended for a dial-up VPN network that requires connections from iPhone or iPad clients. |
Solution |
It should be noted that the VPN is configured as route-based, otherwise known as interface-based. The configuration requires a peer ID ('apple' in this case) as well as a user group. It is best to configure this VPN using the CLI as some of the required settings are not available in the web interface.
Setup a User, User Group, and Firewall Addresses: config user local
edit "testuser" set status enable set type password set passwd <password> end config user group edit "AppleVPNUsers" set member "test" end config firewall address edit "internal1subnet" set subnet <ip here subnet here> (ie: 192.168.29.0 255.255.255.0) next edit "appleVPNsubnet" set subnet 10.3.3.0 255.255.255.0 end Phase 1 Settings:
config vpn ipsec phase1-interface
edit "AppleVPN" set type dynamic set interface "wan1" set dhgrp 2 set peertype one set xauthtype auto set mode aggressive set mode-cfg enable set proposal aes256-md5 aes256-sha1 set peerid "apple" set authusrgrp "AppleVPNUsers" set ipv4-start-ip 10.3.3.1 set ipv4-end-ip 10.3.3.254 set ipv4-netmask 255.255.255.0 set psksecret <tunnel password here> end Optional DNS Phase 1 settings: set domain <domain suffix here> set ipv4-dns-server1 <DNS server IP here> set ipv4-dns-server2 <DNS server IP here> set ipv4-dns-server3 <DNS server IP here> Phase 2 Settings:
config vpn ipsec phase2-interface
edit "AppleVPNp2" set keepalive enable set pfs disable set phase1name "AppleVPN" set proposal aes256-md5 aes256-sha1 end Configure Firewall Policies:
VPN -> LAN: config firewall policy
edit <unique firewall policy ID here> set srcintf "AppleVPN" set dstintf "internal1" set srcaddr "appleVPNsubnet" set dstaddr "internal1subnet" set action accept set schedule "always" set service "ANY" next LAN -> VPN:
edit <unique firewall policy ID here>
set srcintf "internal1" set dstintf "AppleVPN" set srcaddr "internal1subnet" set dstaddr "appleVPNsubnet" set action accept set schedule "always" set service "ANY" end To have VPN clients to access web pages while connected create another firewall policy from the VPN tunnel out of the WAN interface: config firewall policy
edit <unique firewall policy ID here> set srcintf "AppleVPN" set dstintf "wan1" set srcaddr "appleVPNsubnet" set dstaddr "all" set action accept set schedule "always" set service "ANY" set nat enable end Static route to route traffic for tunnel clients back out of the tunnel:
config router static
edit <unique route ID> set device "AppleVPN" set dst 10.3.3.0 255.255.255.0 end Configuration required on the iPad/iPhone Cisco VPN Client:
description: FortiGate VPN.
server: IP of the FortiGate WAN interface that is configured for VPN (interface: wan1 in this case). account: testuser (a user account on the FortiGate) password: <configured previously> Use certificate: off. group name: apple. secret: Pre-shared key for the tunnel, from the phase one step. |
